Hello, when I started up my computer I got a NOD32 update that was quite different from preceding ones I've been accustomed to for years. Basically whereas prior ones were simply automatic updates with the whole "definitions updated" or whatnot, this one was a box which asked my permission to install the update in question. I didn't look too closely at it (it did have some NOD32-looking graphics at the top) but when I clicked yes it began a whole installation thing which basically ended in NOD32 disappearing from my taskbar and when I try to access NOD32 from the start menu I get "Error communicating with kernel." Windows says I have no anti-virus software as well. I figured it might be a virus but when I used Windows Defender and the ESET Rogue Application Remover both came up clean. My computer runs just fine and there's nothing impeding anything, so either: A. I have a fairly advanced virus; B. I should restart to finish the update (seems a bit unlikely); C. NOD32 did something weird and I should uninstall and reinstall. My hard drive has been on a bit of an adventure lately, being affixed as a secondary hard drive to another computer due to Hurricane Sandy knocking the power out of my main computer. I put my HD back into my main computer when power came back on and, besides most things being considered "shared" in status (I had copy-pasted some things from my HD to another when it was a second HD), all seemed fine. Then the nor'easter came and my computer also was without power, so I turned it on (when power was restored, of course) and... well, what I just described occurred. I use Windows 7.
